I want to create a Bluetooth streamer that wirelessly receives audio from a Bluetooth audio player (like smartphone) and then transmits the received audio to a Bluetooth speaker, with no wired connections. Can this be done with a single Bluetooth transceiver like the RN-52? (https://cdn.sparkfun.com/datasheets/Wireless/Bluetooth/rn-52-ds-1.1r.pdf)

  • \$\begingroup\$ Does it say it can do both at the same time? Maybe you need two radios to do two things at the same time? \$\endgroup\$ – old_timer Sep 24 '18 at 3:21
  • \$\begingroup\$ You are looking for a 'repeater', which does not receive and transmit on the same frequencies, and ideally is in the geometric center between the audio player and the speakers. This is something of a shopping question. \$\endgroup\$ – Sparky256 Sep 24 '18 at 4:03
  • \$\begingroup\$ Can a transceiver have two antennas to transmit and receive at the same time? If a transceiver is defined as a transmitter and receiver, why should you assume it has a single antenna? \$\endgroup\$ – donut Sep 24 '18 at 4:18
  • \$\begingroup\$ @donut Actually, very many devices marked as "transceivers" are not capable of transmitting and receiving at the same time, even if they use multiple antennas. The word transceiver comes from a time period, where you had separate transmit and reception units. The transceiver was a single unit which merged both functionalities. \$\endgroup\$ – AndrejaKo Sep 24 '18 at 9:15
